Insertion Operations

Creation operations in SQLite involve the process of adding new records or rows to an existing database table. These operations allow you to populate your tables with data. Let's see how insertion operations work within the concept of creating a database.

Inserting a Record

To create a new record within a table, you can use the SQL INSERT INTO statement. Here's a basic example:

Be careful because this code considers working on an already existing table. If you don't have a users table in your database, then you need to create one.

To avoid the error, you need to create a table in the database with the name users and fields username and email. Only after that can you add records to this table.

Code description

• We connect to the database;
• Create a cursor to execute SQL queries;
• Use an INSERT INTO query to insert a new record into the "users" table, specifying the column names ("username" and "email") and providing values using placeholders (?);
• Execute the query with cursor.execute(insert_query, user_data) and pass the data as a tuple;
• Save the changes to the database using connection.commit();
• Finally, close the database connection.

Insertion operations are an integral part of the "Create" aspect in CRUD, allowing you to create new data within your database tables.
